14 Claims. 122-250) This invention relates to heaters, more particularlyto hot water heaters, and has for an object the provision of a new andimproved heater of this character, and wherein parts thereof are readilyassembled or disassembled, as conditions may require, and when assembledthe parts are securely fastened together.

Other and further objects of the invention will be apparent to thoseskilled in the art from the following description of the drawing inwhich:

Figure 1 is a broken front elevational view, partly in section, of theheater construction,

Figure 2 is an enlarged broken, fragmentary, vertical sectional View,corresponding substantially to the line 2--2 of Figure 1,

Figure 3 is an exploded perspective View of the heater construction,portions of the same being broken away, illustrating the manner in whichthe parts of the heater may be assembled, while Figure 4 is a reducedbottom plan View of the heater base.

As shown in the drawing, the invention com-- prises an elongated outercasing Ill, preferably of sheet-metal, and preferably octagonal incrosssection, at the lower end of which there is provided base means II,carrying an upstanding frame I2, extending along a vertical portion ofthe casing I0.

The base means I I preferably are formed from sheet-metal, having anouter curved depending flange I3, substantially octagonal in plan,merging with an upstanding corrugation or embossment Id, at its innerside terminating in a short flange I5, the embossment I4 at its outerside being octagonal in plan, to conform to the shape of the casing III,the lower edges of the latter being adapted to lie snugly against theouter octagonal surface of the embossment I4 when in position on thebase means II, and to rest upon the flange I3, while the inner surfaceof the embossment I4, is circular in plan to conform to the contour of acircular inner casing hereinafter mentioned.

Seven sides of the octagonally shaped base means are preferablyidentically formed, but an eighth side I6 is differently formed. Theeighth side I6 of the base means I I is formed to provide a depressedplatform I! the ends of which are outer walls of the embossments l8 andI9 merg-- v ing with the adjacent portions of the flange IS,

the embossment I4 of course being mit ed f om the platform area,

The depressed platform IT is provided for the reception of the lower endof the frame I2, the frame I2 having an angular longitudinally extendingflange 20 thereon, shaped to fit within the embossments I8 and I9 and torest flat upon the platform H, the flange 20 preferably beingspot-welded, or otherwise secured, to the platform IT, to fixedly securethe frame l2 to the base means II. Both the flange 20 and platform H areprovided with cut-outs indicated at 2|, for a. purpose presently toappear, the flange I5, heretofore mentioned defining a circular openingin the base means, which communicates with the cut-outs 2|. The frame I2also comprises at the inner opposite ends of the flange 20, spacedvertically extending sections 22, merging at their upper ends with anarched shaped connecting section 23, one side 24 of the casing Ill beingcut out to accommodate the frame I2. The upstanding portions 22, haveinclined outer flanges 25 conforming to the contour of the adjacentsides 26 of the casing I0 and overlie the adjacent edges of the cut-outin the casing Ill, and the arched section 23 is provided with avertically extending flange 21 overlying the adjacent part of the side24 of the casing I0, which defines the casing cut-out, a pair of spacedears 28 being formed adjacent to the junctions of the upright and archsections 22 and 23, and through which fasteners, as screws, may beextended to secure the frame to-the casing I0. integrally formed withthe vertical sections 22 and with the arched section 23 are inwardlydirected webs 29, adjacent the arched section 23 and the upper ends ofthe vertical sections 22, merging into a vertically extended web 38,having an arcuate opening 3l therein, bounded by an integrally formedinwardly directed semi-circular flange 32, the lower ends of the uprightsections 22, being outwardly offset, and merging with the web3ll byoffset portions 34, all defining a socket-like depression for thereception of coil securing means hereinafter mentioned.

-A cylindrical inner casing-35 is disposed within the outer casing Ill,and spaced therefrom, the inner casing 35 having a cut-out 36, and anoutwardly directed flange 31 surrounding the cut-out, the flange 31fitting over the outer surface of the web 29 of the frame I2, while thelower edges of the inner casing 35 bear snugly against the innercircular surface of the embossment I4, and rest upon the flange I5,suitable insulating material being arranged between the outer casing I0and inner casin 35in, a manner well understood in the art.

A top member 38 is provided having a depending flange, octagonal inplan, which fits over the top edges of the cas ng II), the top member38, the base means H, and the interposed casings l0 and being clampedtogether by tie rods All. The top member 38 is provided with an outlet4| for the products of combustion, and is also provided with an openingthrough which the threaded end of the water coil 42 is projected, thelatter being fastened by a nut 53 to the top member 38, the nut 43 notbeing intended to support the relatively heavy coil 42, but merely toposition the same, the opposite end of the coil 62 being provided with athreaded fitting positioned to extend through the semi-circular opening3|, the fitting Al i having'a shoulder 5, adapted to butt against theinner edge of the flange 32, and the threaded portion adapted to receivea nut 46, which lies against the depressed web 30, above the ofisetportions 34, and when the nut M is drawn up, the Weight of the coil ,42is suported partially by the frame I2 as will be understood.

The major portion of the weight of the coil, however, is supported bythe bottom supporting means ti. The bottom means 47 preferably iscircular in outline, dished somewhat to provide a central portion {58,having air vents 49 therein, and a central opening for the passage of agas pipe 56, carrying a burner 55!, inner and outer nuts 52 preferablybeing employed to clamp the gas pipe in position.

outwardly of the central portion 48 the bottom means 41 has ahoriozntally extending fiange 52, adapted to be detaohably secured tothe under surface of the base means H by screw bolts 53 taking throughsuitable apertures therein and adapted to engage suitable threadedbosses in the base means H, as indicated at 5 1, the bottom means 47being of suificient sizeto completelyclose the circular opening in thebase means defined by the flange l5, thereby providing for theinterception and retention of condensation moisture from the coil $22.It should also be noted that by reason of the upstanding nature of theembossment l4, and the manner in which the casings l0 and 35 areassembled therewith, condensation never enters between the casings, andhence the insulation therebetween is maintained in dry con: dition atall times.

Rigidly afiixed to the flange 52 of the bottom means 47 is an upstandi gsupport 55, preferably corrugated, as at 56, to increase its strength,and at its upper end provided with spaced supporting surfaces 51,arranged generally in semi-circular formation, and of a character toengage the under surface of the shOlllder when in position, to providethe principal support for the relatively heavy coil 42, the support 55being positioned to extend between the side sections 22, and rear-Wardly thereof, into supporting engagement with the fitting M whenoperative position.

Once assembled, as described, the relatively heavy coil 32 is supporteddirectly from the base means ll, providing a verystron g and attractiveconstruction. If the coil (l2 should burn out, or become clogged withforeign matter, the coil may be removed merely by loosening the nut G3,loosening the nut 46, removing the screw bolts 53, and dropping thebottom means 41, and coil [22, from the lower ends of the casings l0 and35, the support 55 and fitting M clearing through the cut-out 2|, andthe circular opening defined by the fiange l5 which communicatestherewith, all Without disturbing the fixed structural parts of theheater, and, of course, when the coil 42 has been cleaned, or asubstitute provided, the parts may be re-assembled in the manner alreadydescribed, merely by replacing the same, tightening up the nuts 53 and45, and replacing the holding screws 53.

It will be apparent to those skilled in the art that I have accomplishedat least the principal object of my invention, and it also will beapparent to those skilled in the art that the embodiment hereindescribed may be variously changed and modified, without departing fromthe spirit of the invention, and that the invention is capable of usesand has advantages not herein specifically described; hence it will beappreciated that the herein disclosed embodiment is illustrative only,and that my invention is not limited thereto.
